Who are the Super Bowl X factors?

Cardinals head coaches

Cardinals head coach Ken Whisenhunt knows QB Ben Roethlisberger as well as Steelers coordinator Bruce Arians, from the time Whisenhunt spent in Pittsburgh as offensive coordinator. Plus, Cardinals offensive line coach Russ Grimm has a great feel for the Steelers' offensive line because he coached some of the players on that line when he was the Steelers' offensive line coach. Whisenhunt and Grimm will be able to help Arizona defensive coordinator Clancy Pendergast and offensive coordinator Todd Haley because they used to practice versus the Steelers' defense. They have a good feel for blitz schemes and who to attack in the passing game. On-field adjustments will be critical, and don't be surprised if the Cardinals' coaching staff is one step ahead of the Steelers' staff all day long.
